You can simply Search Applications and gazzom it pull up 2 applications .. click on See All , it will take u to the all applications with icons -- Click on any app icon then AppStore >>Appears in the Path....Click that ! & the Appstore welcomes you .!

1. Just type in the name of a common application, i.e. "AIM".
2. Click the AIM application.
3. The top of the screen has a filetree that has a picture of a house (home)-->App Store-->Social Networking-->AIM. Just click the part that says "App Store" and It will bring you to the main app page.

By the way, I just took some time to browse the store and the result is discouraging. If what I saw (about half of it) is a statistically significant indicator, about 70-80% of the apps present in the store are pure trash. Unintuitive, poorly designed and feature-dry. I REALLY expected to see MUCH more. Sad, sad state of affairs.
